What would Bethesda be without the Mod-Community?

No, I think Bethesda would be fine without modders.

I do like the fact that they allow it, but for the most part, aside from a couple UI mods, I never use mods in Skyrim. I like to play the game that they release, and if I find a weird quirk (they need to do something about the inventory!) then I may through something on, but I don't use anything that changes gameplay, makes things easier, or even adds more content. There is enough content in the game that I could probably go back and play it again and still find new stuff, after many many hours of playing.
